The switch 15 may incorporate with other sensor such as photo sensor so can judge for environment brightness at 3 Lux or 15 lux.

From FIG. 1 disclosure the 2^(nd) switch (Switch 16) OFF switch which can turn off all the light for NO functions at any time.

From FIG. 1 disclosure the 3^(rd) switch (Switch 17) ON/SELECT switch which is turn on one or selected one or all lights of multiple pre-designed light functions to turn on. It can be a silicone conductive rubber switch or other conductive metal switch with cover to push the under PCB which has built-in IC chip so each touch or contact will change function from one to other one. The market place at least has 8 or 16 functions or any number of functions from select

(1) which light turn on or-and

(2) which functions needed or-and

(3) which color needed or-and

(4) automatically to change color or-and

(5) which brightness needed similar or even continuously dimmer or-and

(6) the other functions available from market place.

-   -   So the LED project light has desired number of switch to make         the consumer can do by themselves to make preferred functions         from Multiple functions in one product is much better for one         product only has night light and power fail light.

From FIG. 1 show the optional hold-base which can have built-in AC-to-DC circuit and controller to get DC current and has the DC current output-terminals or ends or contactors to make electric connection with the metal-piece or magnetic-unit or universal magnetic sealed units so can make easily current or electric signal delivery from 120Volt home electricity change to DC current and use DC current to input to the LED project light. The more details and description show on FIG. 8 and FIG. 8A for following discussion.

From FIG. 2 disclosure the LED project light (20) one of preferred construction which may has functions or light type changed or added or reduced but it should be fall within the current invention which has minimum has (AA) project light on center and surrounding of the LEDs unit or COB or SMD or Dip LEDs, and (BB) rechargeable battery inside so can easily charge inner battery or energy storage unit from many other way. The more details discussion show on the Following FIG. 5 for self-built-in Prong, or-and FIG. 8 for hold-base has prong, or-and FIG. 8A for outside transformer, solar module or generator or chemical power or USB power bank through the said connector/adaptor/plug insert into receiving end/socket/port build-in hold-base or the said LED project light housing.

From FIG. 2 disclosure a LED project light (20) has body (21) which has built-in rechargeable battery (24) has positive pole (+) and negative pole (−) to connect with the said rings (25)(26) both is metal or conductive material can delivery electric current or signal. The Ring (25) connect with Negative pole (−) and the Ring (26) is connect with positive pole (+) by conductive wire or piece to build the current delivery. For this preferred embodiment, the two of ring is 360 degree Can contact with the charger circuit's positive and negative pole so can charge the housing (21) inner rechargeable battery (24).

The said inside housing (21) has other preferred or optional other Circuit such as (23″) which has a desired number of LEDs or SMD LEDs or Dip LEDS or COB LEDs (27)(27′) so can make the whole body (21) for body glow. The Body (21) outside surface can has silkscreen printing or laser printing or wrap around by printed piece with art or cartoon or geometric arts so while the inner LEDs (27) (27′) arrange on a circle and emit light toward to upper like the path straight (28) or multiple reflective and refractive path (28′) will make the whole body glow like a back light performance and show out the added printing, logo, art, cartoon, character, image show out on the body.

The said bottom of the housing (21) has built-in (22)(See FIG. 2) or screw in or snap-in or physical push into or screw-in night light (22). The current one of preferred is screw-in type night light (See FIG. 7A) use thread (72 a) (72 a′) to screw into and fit on the bottom of body so can easily to design the circuit which may be connect and get power from the body's internal battery (24); or bottom night light can get power from the self-battery-assembly same as FIG. 7A self-power-assembly (78′) which can be 3 or 4 pcs of LR44 or Bottom batteries with its own switch system (not shown) and circuit with IC chips (72′) with quickly flashing/steady on/random/chasing/sequential or other LEDs light functions to get super long burn time if well control the duty cycles and each on-time v.s. Off-time to get max hundred to thousand hours depend on how to design; and the LED may selected SMD type (77 a) or Dip (77 b) or COB (77 c).

From FIG. 2 can see the top of body (21) has other preferred or optional circuit (23′) and (23). The circuit (23) is reinforce and it is optional to help the bottom circuit (23″) if the LEDs on circuit (23″) is not bright enough, so the Top circuit (23′) can also has multiple LEDs or COB LED to face down to increase the brightness of the lower circuit (23″). Same time the circuit (23′) also can install the IC for multiple or plurality of switch (23′″) (23″″) so can get multiple functions as the above discussed on FIG. 1. The circuit (23′) can install not only LEDs face down but also can install switch PCB so can let outside preferred silicone conductive switch can continuously contact with PCB to make function changed or functions selection. This is very traditional for the Circuit (23′) has one or more PCBs for each of switch for (AUTO) (OFF) (ON) as above discussed on FIG. 1.

From FIG. 2 can see the top head (20) or front part of LED project light has center project magnify assembly including the magnify lens (20 a) and surrounding by the plurality of LEDs or SMD LED or COB (Chip-on-Board) LED (20 c). The magnify lens (20 a) is fit into or sonic-into or assembly-into the flashlight lens (20 b) center. The magnify lens (20 a) is fit with big-cross-section-area outer-tube or bigger Size of diameter outer tube (20 d) and can surround the small-cross-section-area inner- tube or smaller diameter inner tube (20 e) while the head (20) is move away from the body. This kind of magnify-lens (20 a) can move away or close the body (21) can change the magnify lens (20 a) distance with the slide or film or display forming piece inside the smaller diameter inner tube, so can make focus adjustable basing on the FIG. 10 and FIG. 11 and FIG. 12 which shown on the parent filed case or-and co-pending (#FF) U.S. Series Ser. No. 12/914,584 Filed on Oct. 28, 2010 Now is U.S. Pat. No. 8,721,160 which is Division of U.S. Series Ser. No. 12/318,470 filed on Dec. 30, 2008.

It is appreciated all above listed or discussed of all the Parent filed or Co-pending filed case all drawing, claims, description with all alternative or replaceable or equal functions should still consider fall within the current invention scope, spirit, claims.

From the Parent or co-pending filed case (#FF) U.S. Ser. No. 12/914,584 and U.S. Ser. No. 12/318,470 both has the clear project tube with film fit within which is same as current invention for small diameter or smaller-cross-section-area inner tube. The current invention just has move the top magnify or said refractive lens fit into center of the flashlight lens and magnify lens has its own Bigger diameter or bigger-cross-section-area outer tube to envelope or surround or wrap around the small diameter or smaller-cross-section-areas inner tube (Same as all parent filed case for tube) . . . So this is easily to know the said bigger diameter or bigger-cross-section-areas outer-tube just is added length to prevent from LED light beam leakage out to reduce the image projected brightness while the magnify-lens (20 a) is away from original close position to image forming-unit to away position for focus adjustment.

From FIG. 2 and FIG. 3 disclosure the project magnify-lens is fit or assembly or install on the center of the project light front or top lens. It means the magnify-lens is a separated unit. However, for the simple installation or reduce assembly procedure, the magnify-lens on the center of front or top lens of project light can be made by injection process. It only need to design tooling to combine the both (1) front or top project light lens and (2) magnify-lens for one piece tooling so can simple inject one time to get 2 kind of optic-properties lens in one time injection. Or even can combine more optical-properties lens for (a) Projection image or-and lighted-patterns lens, or-and (b) flashlight convex or concave lens, or-and (c) surrounding LEDs or COB-unit(s) for special effects, or-and (d) Even to add laser or hologram treated film or lens in front of the laser light source while the project light device also has built-in laser light source like parent filing above list (#TT-2) U.S. Series Ser. No. 14/968,250 which is CIP of (#TT-1) U.S. Series Ser. No. 14/944,953 filed on Dec. 14, 2015 which is CIP of (#TT-2010) U.S. Series Ser. No. 12/866,832 filed on Sep. 21, 2010

All these parent filed case has built-in Laser-or-and-LED light source. Here did not discuss for hand-held laser related items because too risk for kids use.

From FIG. 3 Top Left corner disclosure the more detail for how to make inner tube (30 e) and outer tube (30 d) from shortest length as top left corner show related to the project magnify lens (30 a) on the center of the Flashlight lens (30 b). The outer tube (30 d) is assembled together with magnify or refractive lens(30 b) so the both is move close or away from the inner tube (30 e) always together to prevent from LED light beam leakage out.

From FIG. 3 top right corner show the said outer tube (30 d) is totally envelope the inner tube (30 e) inside while the flashlight top head (30) is not extended or not move away from the body (31).

From FIG. 3 Lower half center one show the one of preferred extend or move away the flashlight head (30) away from the body (31). The body 921) has neck part (333) which is smaller diameter or cross-section-area than the top flashlight head (30) so the top head can fit into the neck (333) and neck (333) has desired screw tread (longer and much more threads) or other thread (shorter and less number) so can make quickly move the flashlight head (30) to away or back to shortest position to make focus adjustment. The others switch and ring for recharge or delivery electric current already discussed on top and following FIG. 7 and FIG. 7A.

From FIG. 4 disclosure the LED project light head (40) which also is flashlight head (40) that has project magnify lens on center of the flashlight lens as above discussed. The FIG. 4 show the inner tube is one piece with bigger diameter (if while tube is on round or cylinder type, but not limited for current invention). The FIG. 4A show the Bigger outer or smaller inner tube are not single tube which may consist of multiple sections, tubes like telescope from one piece can use more than one sections/tubes with different diameter to get desired longer length, so this FIG. 4A can get longer outer tube if made by more than one of the tube to form the said outer tube-assembly.

From FIG. 4 disclosure the LED project light head (40) has the Film or slide or image-forming-unit (40 e) install on pre-determined positon and while the outer tube (40 d) is away from film or slide or forming-unit (40 e) like FIG. 4 which has longer distance between magnify lens (40 a′) and forming-unit (40 e) than the FIG. 4A magnify lens (40 a″) and forming-unit (40 e″) . . . because the head of the LED project light (40) is extended by screw-thread (444′) on the Neck (444) to extend away from the body top border (40 g) (40 g″).

From FIG. 5 disclosure multiple function LED project light has the lens cover (50 b-1) and adjust focus top head (50) and Glow Body (51) and end light (52) with a multiple selection switch (53) and the built-in prong set to directly plug-into outlet on wall or power strips or extension-cord or where ever had outlet receipts or socket or ports. From FIG. 5 shown top light the prong set is extend out and low light the prong-set is fold into the light body.
